We’ve released skew protection for all plans starting with these frameworks:

-   Astro 5.15.0+
-   Next.js

This feature prevents version mismatch errors when users interact with your site during a deployment.

### What it fixes

When you deploy a new version of your site, users with an open browser tab may still be running the old version. If they navigate to a new page or trigger a request, the browser expects a previous version of your application, but the server returns the new version.

This version skew causes:

-   Broken assets and 404 errors
-   JavaScript errors
-   Degraded user experience

### How it works

Skew protection pins each user session to a specific Netlify deploy, ensuring the browser and server stay synchronized throughout that session.
